Surgical Techniques at Cesarean Delivery: A U.S. Survey.

 To assess the frequency of surgical techniques at cesarean delivery (CD) among U.S. obstetricians.  Members of the American College of Obstetrician Gynecologists were randomly selected and e-mailed an online survey that assessed surgical closure techniques, demographics, and reasons. Data were analyzed using SPSS (IBM Corp., Armonk, New York, United States), descriptive statistics, and analysis of variance.  Our response rate was 53%, and 247 surveys were analyzed. A similar number of respondents either "always or usually" versus "rarely or never" reapproximate the rectus muscles (38.4% versus 43.3%,  = 0.39), and close parietal peritoneum (42.5% versus 46.9%,  = 0.46). The most frequently used techniques were double-layer hysterotomy closure among women planning future children (73.3%) and suturing versus stapling skin (67.6%); the least frequent technique was closure of visceral peritoneum (12.2%). Surgeons who perform double-layer hysterotomy closure had fewer years in practice (15.0 versus 18.7 years,  = 0.021); surgeons who close visceral peritoneum were older (55.5 versus 46.4 years old,  < 0.001) and had more years in practice (23.8 versus 13.8 years practice;  < 0.001).  Similar numbers of obstetricians either reapproximate or leave open the rectus muscles and parietal peritoneum at CD, suggesting that wide variation in practice exists. Surgeon demographics and safety concerns play a role in some techniques.
